Hello Everyone,
I have been sucessfull. Yes, you need to replace at least one of the mSATA drives. I actually did replace only one (because of the reliability, I do not like the RAID 0 solution), as it is not necessary due to the speed of current mSATA drive (I have used Samsung EVO 850) to use RAID 0 anymore.
I have used the Port0 slot.
I removed the mSATA in seccond bay (Port1).
Then you can transfer your current OS, or install a fresh one.
For transferring, I have also couple tricks as it is quite difficult to use this RAID 0 combo outside the computer. If you do not have another SATA 2 mSATA adapter, you can just connect over USB any HDD, make a bit copy (backup) of your currnet system and create a separate USB recovery drive (1GB is enough, as you do not need to include the recovery partition).
Then you just power-off the NTB, remove the SATA 2 2xmSATA ASUS card and while unscrewing both mSATA disks, you start the notebook without anything connected and you will be presented with BIOS. There, you change the sATA mode from RAID to AHCI.
Then you insert your new mSATA drive to the original double mSATA adapter and leave the second bay empty. Then you put it back to NTB and connect the bootable recovery USB.
Then power on. While booting from USB, connect also your HDD with bit copy of the system and follow the recovery procedure from the recovery USB.
Voila, after that, you can sucessfully boot into your old working system running from your new larger mSATA drive.
Unfortunately, I was not yet succesfull in connecting the seccond mSATA drive, as it displays in drive manager as double of its capacity, and is unable to initialise in Windows disk utility stating a CRC error. If you succeed in reusing one of the former RAID 0 drives, write me please, how you did it here.
Best

Jan,
Thanks for the update. I think you are close to the solution. I saw a photo of my disk that I took a while back and it echoes your thoughts. You are right, each of the two mSATA disks (that are custom mounted on to a single drive, in my case) read 3.3VDC. Do you think we can simply replace these existing two mSATA disks with two new high capacity ones? Will that be possible, and will it work?
